するので、加えて回転モーメントの計算が困難になる。Prior Art and the Problems to be Solved by the Invention This type of scale is described, for example, in European Patent No. 005563.
It is known from the specification No. 3. A strain gauge element is provided there for measuring the rotational moment, but this requires a relatively high outlay for electronic evaluation circuits due to the small output signal. On the other hand, a capacitive distance sensor is provided there which measures the horizontal movement of the dish support relative to a fixed point specific to the casing. However, if the structural height of the scale is to be kept low, the horizontal movement in this case is very small and results in a correspondingly small output signal as well. In addition, the often non-linear bends of the link parallel guides are mixed into the measurement results in this case, which additionally complicates the calculation of the rotational moment.

An object of the present invention is to provide an electronic scale with the following features.

内リンクの特性が測定に係ってこない。Means for Solving the Problem According to the invention, this object is achieved in that the lower support is realized in an elastically flexible member, and the load receiver is provided with a substantially flat plate fixed to the member and at least three A spacing detector is fixed to the plate and detects the magnitude of the load and the load.
Operation and effect of the invention solved by the fact that the lower support measures the vertical deflection of the member relative to the plate depending on its position on the loading platform. By using vertical movement,
The distance of the detector from the fixed point of the member can be significantly larger than when horizontal movement is used. As a result, the output signal of the spacing detector is significantly larger and the structural height of the scale is virtually unaffected. By fixing the spacing detector to a plate where the load receiver is fixed to the member, the characteristics of the parallel guide links are not affected by the measurement, since the deflection of the parallel guide links does not change the detector signal. It doesn't come.

するにとどめた。FIG. 2 shows a schematic cross-section of the interior of the balance, with the housing 3 being largely omitted. The weighing device consists of a weighing support l, to which a load receiver 2 is fixed vertically movably via two links 4 and 5 with a fulcrum 6. This load receiver is member 2
transmits a force corresponding to the mass of the article on the scale via the coupling member 9 to the load arm of the conversion lever 7. Conversion lever 7
is supported on the device support l by a cross spring hinge 8. A winding form with a coil 11 is fixed to the compensating arm of the conversion lever 7 . The coil 11 is a permanent magnet device I
0 and generates a compensating force. In this case, the magnitude of the compensation current flowing through the coil 11 is determined by the position sensor 16 and the adjustment amplifier 14 in such a way that a balance is achieved between the weight of the article on the scale and the electromagnetically generated compensation force. is adjusted. This compensation force is applied to the measuring resistor 15,
A measurement voltage to be supplied to the AD converter 17 is generated. The digitized result is supplied to the digital signal circuit 18 and digitally instructed by the instruction section 19. Since these parts of the weighing apparatus of electronic scales are generally well known, they will only be briefly described.

とができる。By the way, the loading platform 34 and the load receiver member 2 are connected through the lower receiver member 20, which is configured to be elastically flexible. This lower support member is connected to the load receiver member 2 on the one hand via a spacer member 27 using screws 28, and on the other hand to the loading platform 3 via a support member 30.
is supported. The deflection of the undercarriage member 20, depending on the magnitude of the load on the carrier and the location of the load on the carrier, is measured by at least three spacing sensors. Only one of these spacing detectors is illustrated as a flat coil 25 in FIG. This coil 25 is fastened on a plate 24 made of insulating material, the load bearing of which plate 24 being also fastened to the component 2 . The coil 25 serves as an eddy current distance detector, and the lower support made of a conductive thin plate measures the distance to the member 20. The coil 25 is connected to the evaluation circuit 13 via a movable conductor 26 . The evaluation circuit derives the interval signal from the change in impedance of the coil 25, as is well known, and the digital signal processing unit 1.
Transfer to 8. Then digital signal processing unit 18
As described in German Patent No. 3,003,862, it is possible to correct corner load errors of parallel guides.

着されている導体路によって形成することもできる。The coil 25 can of course also be formed by a conductor track applied in a spiral shape to the top surface of the plate 24.

すればよくかつ荷台上の荷重によっては負荷されないか
らである。The load receiver is connected to the member 2 via a plate 24 with a distance detector 25.
By fixing the lower support, only the deflection of member 20 is measured, whereas the lower support is dependent on the load of member 20 and plate 24 - e.g. the load receiver is due to the flexibility of the parallel guide link relative to member 2. This change in position does not result in a change in the measurement signal of the distance detector 25. The plate 24 for fixing the distance detector 25 can be constructed thin. This is because the plate 24 only needs to support the distance detector 25 and is not loaded by the load on the carrier.

できる。In FIGS. 4 and 5, an optical spacing detector is illustrated as an alternative embodiment to an eddy current spacing detector. FIG. 4 is a side view, and FIG. 5 is a sectional view taken along the dashed line V--V in FIG. The optical distance detector consists of a light transmitter 32, which is fixed on the plate 24 in block 23, and a light receiver 33, which is also fixed on the plate 24 in block 29. In the optical path between the light transmitter 32 and the light receiver 33, a light shielding plate 31 is provided, which is connected to an elastic lower member. Since the light shielding plate 31 changes the amount of light passing through it when it moves in a direction perpendicular to the optical path, the light receiver 33 can take out an output signal that depends on the interval.

い。The similar types of spacing detectors described so far are, of course, only examples. It is also possible to use other known methods of spacing detectors, such as capacitive spacing detectors, differential transducer 8 reflective optical or fiber optic spacing detectors. Similarly, the lower support shown in FIG. 3 shows only one example of the structure of the member and the elastic structure of the member.
